IMPRovEMl-:N'r IN LUBRlcAToR's Fon AxLEs.

The Schedule referred to in these Letters Patent and making part oi' the same.

To al! whom 'it may concern Be it known, that' I, HENRY THURLOW, of Skaneateles, in' the county of Onondaga and State of New York; have invented certain new. and useful Improvements in Devices for Lubricating Oar- Axles; and I dohereby declare that the following is afull, elear,and exact description thereof', reference being had to theaceom'panying drawing and to the letters of reference marked thereon whichV forma part of this specication.

lThe nature of my invention consists in the construction and 'arrangement of a device for lubricating car-axles,` as will be hereinafter fully set forth.

In order to enable.' others skilled inthe art to' which my invention?appertains to make and use the same, Iwill now proceed to describe' its 'construetion and operation, referring to the annexed drawing, in \vhich-.- 4 p Figure l is a longitudinal vertical section, and Figure 2 is a transversel vertical section of my lubricating attachment.`

A represents a metallic box of any suitable dimensions, provided in the center of its bottom with a small opening having a downward-projecting collar -Bl inside of this box is placed a series of wire springs',G C, the ends of- Which are soldered together witliinthe collar B, and .then spread outwardV below said collar.

A bar, D, running longitudinally through the box, near the top,` holds thesprings down, and prevents them from moving up, when the cars are `in motion, to dist-urb the lid of the box.

This attachment-,Fis filled with tallow or other suitable.V grease which will remain in the solid-state, and is there t fastened on the present ear-box by means of small-screws; the wires O O passing down through the car-box 'and resting on the axle. `The axle is then oiled in the usual manner. A

After the car has been run. until the oil in the old box isex-hausted, the axle becomes warm and dry and heats the wires. They convey the heat to the grease contained in the attachment, and it melts and-follows the wires dowu to the axle,keeping it well greased and cool;.

, On reaching a slation, ii'an attachment is fono@ empty 01" nearly so'it can 4b'e removed and another a l I afx my signature in the presence ot' two witnesses.
